Frustrated. I went through the software update troubleshooter 100x and finally figured out where to go for a USB version of the update... but when I go to tvupdate.roku.com and I enter the model and serial number of my TV, it says my model doesn't exist. I've had this TV just under a year. This is ridiculous. What can I do?
Are you entering your Roku serial number (as displayed under Settings->System->About) or your onn serial number? If I enter your model number and my TCL TV Roku serial number (just to enter a valid serial number) I get back:
"Confirmation - 55" onn. Roku TV (UHD)
Your Roku TV is a onn. model 100012586-CA. Is this correct?"
